Embodiment Construction

[0037] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0038] First, several nouns involved in the embodiments of the present invention are introduced:

[0039] 1. The first picture: one of the picture to be detected and the original picture.

[0040] 2. The second picture: the other one of the picture to be detected and the original picture.

[0041] Wherein, the picture to be detected may be an unprocessed picture, or a picture obtained by processing the original picture, and the picture to be detected includes but is not limited to the following pictures:

[0042] (1), the image obtained by cutting the original image;

[0043] (2) A picture obtained by compressing or stretching the original picture in equal proportions;

[0044] (3) A picture obtained by non-proportional compression ...

Abstract

The invention discloses a similar picture recognition method and a computer device, belonging to the technical field of image processing. The method comprises: obtaining n first local regions having affine invariant properties of the first picture and m second local regions having affine invariant properties of the second picture, then, the first eigenvalues corresponding to n first local regionsand the second eigenvalues corresponding to m second local regions are obtained, and whether the first picture and the second picture are similar or not is identified according to the comparison results of the n first eigenvalues and the m second eigenvalues. By extracting a plurality of local regions with affine invariant property in a picture, the invention converts the comparison of two pictures into the comparison of eigenvalues of two groups of local regions, thereby enabling the similar picture recognition method to have good anti-clipping property, and improving the recognition accuracyof the similar picture while improving the detection dimension.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of image processing, and in particular, to a similar picture recognition method and computer equipment. Background technique [0002] With the development of information technology, similar image search is a hot spot in the current search field, and it is usually used in image search services or image copyright identification services. The premise of similar image search is the identification of similar images. [0003] In related technologies, the method for identifying similar pictures includes: the server respectively obtains the first feature value of the first picture and the second feature value of the second picture through a preset algorithm, and then the server compares whether the first feature value and the second feature value are the same , to determine whether the two images are similar. Wherein, the first feature value and the second feature value may be hash values...
